INVENTORS F. THOMAS COLSEN BY PETlER KAUFMAN ROBERT L. TOWNSENDATTORNEYS AUTo ALARM SYSTEM BACKGROUND OF THE INVENTION Numerousautomotive alarm systems have been proposed. Most of them involvesubstantial modification of one or more existing automotivesubassemblies, requiring additional tooling for production and finalassembly. Further, the presence of many alarm systems on an automobileis immediately obvious. Since no system is completely foolproof, areadily detectable system is less desirable then one which is notconspicuous. Other alarm systems are unsightly or inconvenient for theautomobile owner to use.

More recently, an automotive security system which is totally controlledby the ignition/door key has been developed. This application is thesubject of US. Pat. application Ser. No. 188,456, filed Feb. 24, 1971,the

disclosure of which is expressly incorporated herein by l reference.This system is armed by locking and disarmed by unlocking thedriversdoor with the key. The interior door lock button has no effect on thealarm. When the alarm is armed, any access gained to the car whichactivates the courtesy or dome light circuit and/or hood or trunkswitches will sound the horn and/or blink the lights intermittently fora predetermined length of time and then shutdown automatically. Thealarm, once activated, can be shut off by unlocking the drivers doorwith the key and then activating the ignition with the key for a briefperiod. Any attempt to cut the wires leading from the door to the cowlarea will not affect the alarm once it is activated. If the opened dooror deck lid, which set of the system, is not-closed, the alarm willcontinue to sound indefinitely. Two of theprimary advantages of thesystem are its ease of use and integral design which, because ofpackaging, is not physically discernible to a would-be intruder.Thecomponents are easily installed with no appreciable change toexisting hardware or packaging on most models. The tumbler switch isself-adjusting and may be bench assembled to the door lock tumbler forloading into the door through the door lock tumbler hole.

The present invention is concerned with a significant advance in the useof the door/ignition key to arm and disarm an automotive securitysystem.

In the system of this invention, arming or activation is achieved bylocking either front door with the door/ignition key. The system is notactivated when the door lock buttons are used to lock the doors. It isnecessary tolock only one door with the key to arm the system. Thesystem is disarmed by unlocking either door with the key. The remainingdoors may be opened in conventional manner with door lock buttons. Whenthe system is armed, it is triggered by the opening of the doors, hoodand/or trunk to sound the horn or blink any one or more of theautomotivelights. The system can be made to shut down automatically after adesired predetermined time. The system once triggered may be deactivatedby simply inserting the key in the ignition and turning to the accessoryor on" position. This system is fully compatible with existing tumblerand other door hardware including all of the tumbler devices shown inthe above-identified copending patent application. It is to beanticipated that the present invention which solves numerous,longstanding problems in this art, will be rapidly and widely adopted.

. tivated by said key to cause a momentary current to SUMMARY OF THEINVENTION an arming circuit, and a disarming circuit, said arming anddisarming circuits being closed by switches acpulse said armable circuitinto either the armed or disarmed mode, said armable circuit, when inthe armed mode, being triggered by at least one automotive courtesy ordome light switch, hood switch or trunk switch to complete the circuitallowing current to flow through said circuit to said automotive lightsand/or horn.

In general, it is an object of our invention to provide a novelautomotive'alarm system which is fully compatible with existingautomotive tooling and assembly procedures, is not readily detectable,can be activated by the door/ignition key, and is uniquely simple forthe automotive owner to use.

More particularly, the main object of this invention is the provision ofan automobile safety alarm system which can be armed and disarmed ateither front door or any lock tumbler switch, and when triggered, can beshut down solely by the operation of the ignition switch.

These and other objects and advantages of the present invention will beapparent from the following detaileddescription and the accompanyingdrawings.

FIG. 9 is a wiring diagram showing the installation of the system in anautomobile.

Turning to the drawings in greater detail, in the em bodimentspecifically illustrated in FIG. 1, the device comprises an integralring 10 having an opening 12 adapted to receive the lock tumbler 14. Thering 10 carries magnet 16 and pin 18 which is received in acomplementary slot (not shown in this view) on the underside of tumbler14. The switch. assembly 20 is proone positioned at point 24 and theother at point 26. Said switches are provided with leads 28, 30 and 32.

The lock tumbler 14 is provided with a conventional chromed bezel 34.The tumbler is operated by door key 36. All parts shown in FIG. 1 savethe bezel and key are normally contained within the automobile door (notshown). The tumbler has a projecting shaft 38 and associated key 40. Theconventional latch lever 42 has an opening 44 which snugly receives theend of shaft 38 and key 40. The other opening 45 in lever 42 receives anoperating rod 47 which leads to the door lock mechanism. The keeper 46is received on the end of shaft 38 with a snap fit to complete theassembly of that portion of this invention normally carried by theautomobile door.

The inner workings of tumbler 14 are well-known and do not form a partof this invention. Hence, they are not described in greater detail inthis patent. Likewise, the operation of the lever 42 and the operatingrod are as in existing automobiles.

The wires 28, 30 and 32 are part of the circuit shown in greater detailin FIG. 5, hereinafter discussed in greater detail.

Turning to FIGS. 2 and 3, the lock tumbler 100, bezel 102, key 104,latch lever 106, key 108, keeper 110 and operating rod 112 are describedabove. The ring 114 has a magnet 116 and pin 118 which is received inslot 120 of the cam 122. The switch assembly 124 is provided withinternally carried switches at either side. The function of leads 126,128, 130 and 132 is discussed below.

The following relates to FIG. 5.

ARM

To arm or activate the alarm system, a pulse on the order ofmicroseconds or more is required from the door signal (pin 400) throughthe door switch to arm or activate pin 402. During this time periodcurrent flows through resistor 404 to the door switch, through the doorswitch and into pin 402 passing through diode 406 which is a negativespike protector into the gate of SCR 408. Resistor 407 is associatedwith diode 406. The gate-cathode of SCR 408 acts like a diode supplyingbase current through resistor 410 and diode 412 to transistor 414saturating transistor 414. With transistor 414 saturated, current flowsthrough resistor 416 saturating transistor 418. Transistor 418 suppliescurrent through the turned on SCR 408 to the rest of the circuit withresistor 420 providing minimum holding current.

DISARM To unlatch the alarm system a pulse on-the order of 10microseconds or more is required from the door signal (pin 400) throughthe door switch to disarm (pin 422). Current flows into pin 422 throughresistor 424 and diode 426 (negative spike protector) into the base oftransistor 428 saturating transistor 428. When the base of transistor428 is saturated, drive is removed from transistor 414 turning offtransistor 414 which turns off transistor 418. With transistor 418 off,zero current flows through SCR 408 which turns SCR 408 off and theentire system is off.

TRIGGER SIGNAL When the system is armed, a +12 volt signal received fromthe courtesy light group, trunk or hood switch will trigger the system.The gate of SCR 430 is then pulled high through resistor 432 or resistor434 turning SCR 430 on. SCR 430 now'supplies power to several functions.

1. Resistor 435, diode 438 into the gate of SCR 440 turning on the horn.The flasher 442 cycles the horn power.

2. Resistor 444 for SCR 430 holding current.

3. Resistor 446 to the base of transistor 448 saturates transistor 448to remove any latch turn-off current from having effect.

4. Time out circuit comprised of resistors 434, 436,

. 450, 452 and 453, capacitor 460 and programmable unijunctiontransistor 456. Diode 458 is placed in series with the tum-off functionsof the system to protect these functions from voltage transients inducedby the horn, or other transients produced elsewhere in the automotiveelectrical system.

TIME OUT The programmable unijunction 456 can be set for a predeterminedtime constant by resistor 450 and capacitor 460. When the charge oncapacitor 460 thresholds transistor 456, a positive pulse is sentthrough resistor 462 to saturate transistor 428 and the normal disarmsequence follows.

IGNITION TURN OFF The ignition switch applies +12 volts to pin 464causing current to flow in resistor 466 and into the base of transistor428 initiating the normal disarm sequence.

Diode 412 in the base of transistor 414 insures that the saturatedvoltage drop of transistor 428 is less than the combined forward voltagedrop of base-emitter junction of transistor 414 and diode 412. Resistors468 and 470 are gate protect resistors for SCR 408 and SCR 430.Capacitor 454 is a transient protect capacitor for SCR 430. Capacitor472 is a transient protect during starter engagement and disengagement.

Turning to FIG. 4, each tumbler is provided with an arm lead 300, disarmlead 302 and common or door switch lead 304. These leads are connectedto the arm and disarm portion 306 of the circuit. The triggering.

portion of the circuit includes the activate circuit 308, ANDGATE 310,and ORGATE 312, which response to the opening of the luggage compartment314, hood 316 or operation of the dome light 318. When triggered, thehorn power circuit 320 operates the flasher 322 which intermittentlyblows horn 324. Circuit 308 goes to timing circuit 326 which operatesthrough ORGATE 328 and then through clear line 329 to arm and disarmportion 306. The shut-down can also be accomplished by ignition switch330. Hold-off provided by line 332 prevents the disarming of thetriggered circuit by turning the tumbler to the disarm position, and/orcutting the wires to the door.

In the embodiment of FIGS. 6-8, the tumbler 200, key 202, bezel 204,ring 206, key 208, keeper 210, operating rod 212, magnet 214 and latchlever 215 are as previously described. The switch assembly 216 containstwo reed switches 218 and 220. The assembly is attached to the tumblerclips 222. The assembly 216 is provided with leads 224, 226, and 228.

In operation, the system is armed by inserting the door key in thetumbler and turning the same to the lock position and then back towithdraw the key. The engagement of pin 118 in slot causes the magnet116 to turn or rotate with the key 104. The magnet momentarily closesone of the switches causing a current to pulse the armable circuit intothe armed mode. In the armed mode, the system draws less than 0.025amps, and zero amps in the disarmed mode. Use of the key to unlock thedoor causes a current to pulse the armable circuit to the disarm mode.Arming and disarming can be carried out with the door key at any door orlock tumbler provided with the switch system.

It should be noted that the system of this invention eliminates the needfor a horn relay.

Many variations of our invention are contemplated. For example, the hoodand trunk may or may not be included in the system. The alarm systemneed not contain both horn and lights. One or the other alone may beused in the system.

The invention is not limited to any particular type of switch. As willbe obvious to those skilled in the art, other switches may be adapted tothe system to pulse the system.

Likewise, many variations of the transistorized circuitry of thisinvention will be apparent to those skilled in the art which willprovide the unique operation and results of the system. In addition, thecircuit can be in the form of an integrated circuit or anelectromechanical system.

Having fully described the invention it is intended that it be limitedonly by the lawful scope of the appended claims.
